COAL-WASHER.

Specification of Letters Patent.

Patented May 17, 1921.

Application. filed February 11, 1921. Serial No. 444,179.

To all 'whom z'zf may concern."

Be it known that we, WILLIAM BRINLEY and WALTER COLLINS, citizens of the United States, and residents of Benton, in the county of Franklin and State of Illinois, have invented certain new and useful Improvements in Coal-Washers, of which the following is a specification.

Our invention refers to improvements in apparatus for washing coal and similar materials, wherein separation of the coal and .impurities contained therein is effected by the combined action of gravity and the buoyancy of water when subjected to a series of pulsating movements, and more particularly relates to the construction and arrangement of thecoal jig, as will be more fully described hereinafter.

One object of our invention is to construct a coal washing apparatus having novel means whereby the parts most liable to wear or break are located in accessible positions and renewals or repairs thereto thereby facilitated.

Another object of the invention is to so locate the bearings and other like parts, so that they will not be subjected to wear and consequent damage, by coming in contact with the material beingwashed orv refuse washed from the material.

A further object of our invention is to provide a washing apparatus of generally improved construction, having the novel constructions, arrangement and combination of parts shown in the drawings, to be described hereinafter, and to be particularly v pointed out in the appended claims.

Referring now to the drawings forming part of this specification, Figure 1 is a sectional side elevation, showing a washer or jig constructed and arranged in accordance with our invention.

Fig. 2 is a sectional end elevation of the apparatus of Fig. 1, the section being taken on the line II--II of Fig. 1.

In the accompanying drawings, the 11umeral 2 designates a tank or receptacle, which is preferably rectangular in horizontal cross-section, this tank having inwardly and downwardly sloping ends 3, 3, and a middle transverse partition wall 4. The one end wall 3Vis of less height than the surrounding walls, thus providing an overflow ledge 26 over which the washed coal will escape. j

bottom' of the tank is provided with an opening 28 to allow for the removal of the foreign matter washed from the coal.

Screens 5-and 6, which are formed of bars, perforated plates, wire netting or the like, are mounted in the upper portion of the tank, and are adapted to support the material to be washed and to provide for free u ward travel of the water therethrong in the pulsations caused by the action of the reciprocating plunger hung be low the screens. The screens 5 and 6 are rigidly secured in position and are preferably arranged at a slight angle, as shown, inclining downwardly from the ends toward the vertical center of the A cross support 10 is arranged between the screens 5 and 6 and is secured in the side walls of the jig. A second cross support 11 is mounted on top of the wall 4c, and a suitable wooden pendulum plunger is mounted between the timbers 10 and 11, being pivotally supported on the shaft 12.

The plunger preferably is formed of a plurality of layers of wood suitably secured together to form a rectangular body portion 13, and this plunger 13 has upwardly projecting arms 13a formed at each end thereof. Metal straps 111 secured along each side of the plunger and along the comparatively narrow arms, reinforce the arms and form hinges or hangers for the swinging plunger 13.

Dead eye bearings 15 are secured to the upper ends of the hangers, these bearings joining the strips 14, and having openings therein to receive the shaft 12, this shaft being mounted in suitable bearings 16 on the pedestals 16'r1 formed on the top surface of the jig or tank walls.

Housings 15a conveniently formed of sheet metal are arranged around the portion of the hangers above the screens 5 and 6 to prevent material being washed from striking and damaging the hangers, and to prevent material which is being washed from escaping from the screens through the holes through which the hangers pass.

Suitable plunger rods 17 Y and 17a are pivotally connected to heads 18 mounted on the one side face of the plunger, and eX- tend outwardly through suitable stuiiing boxes 19 and glands 19a in the end wall of the jig, and have their other ends connected to the rocking blocks 2O of the cross-heads 21. Plunger rods 17 land 17"l are provided intermediate their ends and within the tank 2 with a pivoted joint 17h to allow for the swing of the plunger and permit the plunger rods to move freely through the stufling boX 19.

The cross-heads 21 are reciprocated by the eccentric rods 22, these rods having one end secured to a cross-head 21, the other end being adjustably connected to one or the other of the adjustable eccentrics 23, on the eccentric shaft 24. The eccentrics 28 are made adjustable, as shown, in order to vary the throw7 of the eccentrics, and in this way vary the swinging movement of the plunger.

In the position shown in Fig. l, the plunger is at its middle position and is adapted to reciprocate to the same extent on opposite sides of the vertical center of the position l. Such reciprocation of the plunger produces a series of pulsations, causing the water in the tank 2 to surge upwardly alternately through the perforated screens 5 and 6, and effectively wash the coal introduced on top of the screens.

The coal to beV washed is supplied to the 'jig through a conduit or spout 25, from any suitable source, so as to provide a continuous regulated supply.

Water is supplied to the tank 2 through valved pipes 2?, any number of which may be used in order to supply sufficient water for washing the coal.

The coal delivered to the jig contains foreign matter, slate, and other impurities. As the water is forced up through the screens 5 and 6 the coal is carried by the water over the overflow ledge 26, and the foreign matter, such as slate being of greater specific gravity than the coal, settles or falls and the major portion of such matter will escape through the screens 5 and 6 and settle in the bottom of the jig tank where it may be removed through the opening 28 byr a dewatering continuous bucket elevator r the like. Any of the foreign matter remainingkon the screens 5 and 6 may be removed by shovelingV or otherwise, as desired.

rThe many advantages ofcoal washers employing our improved pendulum plunger construction will be readily apparent to those skilled in the art.

It will be understood that the swinging movement of the plunger may be v ried in extent and in speed, to suit the character of Y the material being washed, and also that the slope of the screens may be changed, and other changes made without departing from the spirit of our invention, as defined in the appended claims.

l. Coal washing apparatus, comprising a tank, a pair of coal. supporting screens ar ranged transversely of the tank and sloping upwardly and downwardly from the ends thereof, a pendulum plunger having upwardly exteniiling hangers formed integral therewith and journaled on a` transverse shaft, said shaft being mounted in bearings located above the tank, and means for oscillating said plunger.

2. Coal washing apparatus, comprisinga tank, a pair of coal supporting screens extending across the upper end of the tank. a pendulum plunger having upimrdly extending hangers, said hangers being journaled on a transverse shaft above the upper edge of said tank, plunger rods connected to the said plunger for oscillating the same, and, on the exterior of the tank, means for actuating said plunger.

3. In a coal washer, a tank to contain water for washing coal, and having a. screen for supporting the coal, a pendulum plunger for producing` a series of pulsations in the water in said tank, to thereby cause, the water to surge upwardly through said screen alternately on opposite sides of said plunger, said plunger comprising a substan tially rectangular body portion below said screen, and having upwardly projecting arms at each end thereof, bearings on the upper end of said arms, a shaft extending across the top of said tank on which said bearings are mounted, and means for oscillatino` said plunger.

4. 2ln a coal washer, a tank to contain water for washing coal, a screen in the upper end of said tank for supporting the coal being washed, an oscillatory plunger for producing pulsations in the water, and cause surging thereof upwardly through said screen alternately on opposite sides of said plunger, said plunger comprising a substantially rectangular body portion below said screen and having upwardly projecting arms at each end thereof, metallic straps extending along each side of said plunger body and said arms, hearing members secured to the upper ends of said straps, a shaft passing through said bearings and mounted on top of said tank, and means for oscillating said plunger.

In testimony whereof we have hereunto set our hands.
